Plumber Invoice Template: What to Include and What to Skip
A clean plumbing invoice template that gets paid on the spot — with line items, fees, and warranty language.
Always charge for the diagnostic
Make it visible on the invoice. If they approve repair, credit it back. This makes the diagnostic feel fair instead of a hidden surcharge.
Itemize fixtures and parts separately
Customers trust you more when they see PEX fittings, valves, and labor split out — even if your total is the same.
